on 12

A standard scale from 1 to 10 used to judge how hyper, loud, or energetic someone is. When out with friends for the night, and someone is being exceptionally loud and annoying, they are "on 12".

Lucy: Is Maria coming out?
Mike: Yeah but that bitch is on 12 tonight!

12s

The Seattle Seahawks' dynamic fan base. Regarded as the unrivaled loudest, proudest, most enthusiastic fans in the history of the NFL.

The 12s were in full force at Super Bowl 48; their crowd noise caused the safety to open the game because the Denver Broncos could not hear the snap count.
